[X86][SSE] Simplified PSUBUS tests
Removed loops from PSUBUS tests - ensures folding is tested. Also renamed SSE2 tests SSSE3 to match cpu. This is a follow up commit agreed in http://reviews.llvm.org/D7094 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226871 91177308-0d34-0410-b5e6-96231b3b80d8
